wing plate

14 and 15 obtains according to each roller of landing door.Therefore, the height in gap must be substantially equal to the height in a district between the

wing plate

14 and 15.

Fig. 1 shows from the arrow of point of connection 3 beginning and " closes " and " unlatching ".Close arrow point out when door when closing wire drive pull a door direction (among the figure left), point out that when door is being opened wire drive pulls a direction (among the figure to the right) and open arrow.Close arrow and also point out the direction of the closing movement of door, and open the direction that arrow is also pointed out the breakdown action of door.In Fig. 1, operating lever 5 is shown by a sector 6a who is drawn in pivot 6 places around the angle that pivot 6 conter clockwises turn over when Abseiling device is attempted to open.The rotation of some

other parts

7,8,9 is shown by sector 7a, the 8a, the 9a that are illustrated on each suitable part in the linkage that is caused by the rotation of operating lever 5.These

parts

7,8,9 of linkage rotate around pivot 7b, the 8b motionless with respect to door coupler, 9b.These

pivot

7b, 8b, the 9b motionless with respect to door coupler are shown by (blacking) circle that tamps in each figure.Every other pivot and the point of connection motionless with respect to door coupler are also all shown by the circle that tamps.Each pivot that moves with each part of linkage and each point of connection by hollow (white } circle shows.Fig. 2 show each part of linkage, each wing plate 14 of door coupler and 15 and lock bolt 10 because the last position that arrives of effect of the linkage that causes because of the action of operating lever.

Below the operating lever 5 that turns over sector 6a is come from explanation exercise effect be how among linkage 2, to transmit.Operating lever 5 is connected in linkage via three

moveable pivot

5x, 5y and 5z.One supporting lever 21 is arranged below operating lever 5, be connected in a motionless pivot 2la rotationally and on it, have movable pivot 21x and 21y.Lay respectively between pivot 2la and the 21x and the lever arm between pivot 6 and the 5x has equal lengths.Equally, lay respectively between pivot 2la and the 2ly and the lever arm between pivot 6 and the 5y also has equal lengths.Left side wing plate 14 is connected in operating lever 5 and supporting lever 21 via pivot 5x and 21x.One synchronizing bar 16 is connected in control lever bar 5 and supporting lever 21 via

pivot

5y and 21y, and its mode is that

pivot

5x, 21x, 5y and 21y constitute each angle point of a parallelogram, so that left side wing plate 14 is parallel to each other with synchronizing bar 16; Between pivot 2la and the 21x and the lever arm between pivot 6 and the 5x be parallel to each other; And the lever arm between pivot 2la and 21y and pivot 6 and the 5y is parallel to each other.In fact, with regard to its various motions, synchronizing bar 16 corresponding to the wing plate of wing plate 15 corresponding one common door couplers, and this wing plate 15 as a slip wing plate that activates lockset, is one of synchronous straight-bar 16 independently (detached) surface element, when it leaves with synchronous straight-bar 16 next-door neighbours regional, prevent that lock bolt 10 from getting loose, the left end of a first connecting rod 22 is connected in operating lever 5 at pivot 5z place, and operating lever 5 is connected in a top culdy 7.This connecting rod has an articulated joint 22a between its two ends, allow the connecting rod bending.Top culdy 7 is supported by a motionless pivot 7b.Round this pivot 7b, the top culdy has the point of connection that pivot 7x, 7z and are used for the extension spring 23 that moves with culdy.Connecting rod 22 right-hand members are connected in uppermost pivot 7z.When connecting rod 22 rotated along clockwise direction along with operating lever 5 and moves right, culdy 7 also clockwise rotated.This clockwise rotates by extension spring 23 and gives assistance, and the latter applies a pulling force at point of connection 7y place, the right side, acts on the downward direction of extension spring point of connection 23a on the suspension plate.If connecting rod does not have articulated joint 22a, just do not needed extension spring 23 yet.The left side pivot 7x that causes on the culdy 7 that clockwise rotates of first culdy 7 moves up, thereby the right moveable pivot 8y of one second culdy 8 is pulled to the top by means of a second connecting rod 24, cause culdy 8 to rotate around pivot 8b inhour, the result is that left side pivot 8x moves right.The first end of second connecting rod 24 is connected in pivot 7x, and the second end is connected in pivot 8y.Pivot 8b, the 8x of

culdy

8,8y are positioned near each drift angle of culdy 8.

In fact, the above explanation of the various motions of the various parts of linkage be applicable within the landing zone and outside, and when the door control benchmark (door control reference), in other words, the pulling force that is produced by door drive is when closing direction changes to opening direction, and various motions are owing to the angle that operating lever 5 turns over corresponding to sector 6a takes place.

Referring now to Fig. 1 and 2,, a kind of situation will be described, this moment, car was positioned at outside the landing zone, then referring to Fig. 3 and 4, another kind of situation was described, and this moment, car was positioned within the landing zone.

One third connecting rod 25 is connected in pivot 8x on the culdy 8 by its first end.This third connecting rod 25 is secured to the right-hand member of a L shaped basically locking lever 11 rotationally via the pivot 25a between its two ends.This locking lever 11 keeps transfixion basically, and this point is guaranteed by a compression spring 12, and this spring applies one to the left end of locking lever and upwards pressure, and itself presses lock bolt 10 towards latched position again.Each drawing only shows

spring

12 and 23 in Fig. 1.Along with making connecting rod 25 first ends that are connected in pivot 8x, culdy 8 moves right, connecting rod 25 rotates around pivot 25a, the result is, the second end of this connecting rod is moved to the left, and apply a power via the pivot 27a of one the 4th connecting rod 26 between first suspended levers, 27 two ends of wing plate 15, cause described lever 27 to turn left.The first end of the 4th connecting rod 26 is connected in the second end of third connecting rod 25 via pivot 25x, and the second end of the 4th connecting rod 26 is connected in the pivot 27a on first suspended levers 27.Wing plate 15 is connected in door coupler via two suspended levers 27 and 28.First suspended levers 27 and second suspended levers 28 are connected in the suspension plate 1 that is supporting door coupler at their each first end place rotationally via

pivot

27x and 28x, and each pivot is motionless with respect to door coupler.Suspended levers 27 and each the second end of 28 are connected in wing plate 15 via pivot 27y, 28y.Two suspended levers 27 have identical length with 28.

Pivot

27y, 28y, 27x and 28x relative to each other and with respect to suspension plate 1 so are provided with, so that when suspended

levers

27,28 was rotated, wing plate 15 was still to just on vertical direction.Thereby, when car in the landing zone beyond the time, the action of the linkage lockset that can not get loose, and just cause wing plate 15 to shift to left.Compression spring 12 guarantees that wing plate can shift to left.Because by the strength that compression spring applies to locking lever 11, pivot 25a still is actionless when pivot 25x moves.

Referring to Fig. 3 and Fig. 4, a kind of situation is described now, wherein car is within the landing zone and the locking of car door is released.

Fig. 3 shows that the sector 6a at pivot 6 places at first rotates the angle that turns over to get loose lockset at anticlockwise direction to point out operating lever 5, and operating lever 5 then rotates another sector 6A that turns over to allow door coupler 4 to engage the roller 17,18 on the landing door.

In the above described manner, the action of linkage also produces the rotation of

culdy

7 and 8 inter alia, as the sector 7a and 8a on each lever top as described in being drawn in shown in.Because the right wing plate 15 presses the right roller 18 when car is in the landing zone within the time, certain of the various parts of linkage a few is being different from the manner of execution when car be in the landing zone in addition in.As mentioned above, roller 18 can be described as a fixing roller, and in other words, it is one and keeps motionless roller basically on respect to the horizontal direction of landing door when the door coupler wing plate presses it.On the other hand, roller 17 can move past a certain distance with respect to the landing door, so, the motion that pressure produced that puts on this roller by door coupler wing plate 14 can be used for the getting loose lockset of landing door.When wing plate 15 is pressed against roller 18, just can prevent that it from shifting to left.Being third connecting rod 25 about an important action of expection operation turns over by the clockwise rotating of an indicated angle of sector 25A around pivot 25x, this action since culdy 8 inhour rotations take place.

Fig. 4 show linkage 2 each part, door

coupler wing plate

14 and 15 and lock bolt 10 owing to turn over the last position that arrives of action of a linkage that causes corresponding to the angle of sector 6a because of operating lever.The first end of connecting rod 25 is connected in the pivot 8x on the culdy 8, and its lower end is connected in the 4th connecting rod, and is shifted to the fulcrum that is used as its rotation when right-hand at the pivot 25x at place, its end by culdy when its upper end.Because the motion of the right wing plate 15 and thereby also have the motion of suspended levers 27 to be stoped, so, the motionless basically fulcrum that the pivot 25x at the 4th connecting rod right-hand member place rotates as third connecting rod 25.In the case, the effect of compression spring 12 on lever 11 by pivot 25x the supporting power indirectly accepted exceeded.Therefore, the pivot that connects between the two ends of the third connecting rod on it of L shaped locking lever 11 is pulled through certain distance to the right.The pulling force that causes by the motion of locking lever 11 lock bolt 10 that got loose, thus allow the breakdown action of beginning car door.Simultaneously, a safety switch 13 that is provided with in conjunction with lock bolt 10 is opened.One shows that the electric signal whether car door locks is fed to vital circuit from safety switch, and if desired, feeds to the control system of elevator.After lockset gets loose, operating lever will further turn over the segment distance corresponding to sector 6A shown in Figure 3.The This move of operating lever makes the right door coupler wing plate 14 move and contact the right roller 17 on the landing door and door coupler roller 17,18 is pressed between the door

coupler wing plate

14,15, causes connecting fully of landing door and car door.Operating lever freely turns over sector 6A, because connecting rod 22 is provided with a hinge-point 22a, allows this connecting rod bending so that its to be received towards the complete basically bending by connecting rod of moving of culdy 7 after the lockset that gets loose.
